Answer:
$1.10
Step-by-step explanation:
We have been that Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change.
First of all, we will find amount paid for 5 avocados by subtracting $4.50 from $10.
![\text{Amount paid for 5 avocados}=\$10-\$4.50](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20paid%20for%205%20avocados%7D%3D%5C%2410-%5C%244.50)
![\text{Amount paid for 5 avocados}=\$5.50](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20paid%20for%205%20avocados%7D%3D%5C%245.50)
Now, we will divide $5.50 by 5 to find cost of each avocado.
![\text{Cost of each avocado}=\frac{\$5.50}{5}](https://tex.z-dn.net/?f=%5Ctext%7BCost%20of%20each%20avocado%7D%3D%5Cfrac%7B%5C%245.50%7D%7B5%7D)
![\text{Cost of each avocado}=\$1.10](https://tex.z-dn.net/?f=%5Ctext%7BCost%20of%20each%20avocado%7D%3D%5C%241.10)
Therefore, the cost of each avocado is $1.10.
One solution was found : t ≤ -13 (number 4)
Pull out like factors :
-3t - 39 = -3 • (t + 13)
Divide both sides by -3
Remember to flip the inequality sign:
Solve Basic Inequality :
Subtract 13 from both sides to get t≤−13
Answer:
Option A is true
The researchers proved that exercise causes weight loss only for high school students.
Step-by-step explanation:
We are told that the researchers found a high correlation, 0.93, between amount of exercise and weight lost.
Now, looking at each of the options;
- A is True because due to the high correlation, the research proves that exercise causes weight loss but only for high school students.
- B is not true because we are told the correlation is very high at 0.93. Thus, it is untrue that there is no proven causation.
-C is not true because there's no where that the researchers have completely proved that exercise causes weight loss generally. It is only peculiar to the high school students studied.
-D is not true because the 93% is just a correlation and not a percentage of those who lost weight
If 1/3 = 12, then multiply 12 by 3 to get the number, which is 36
then split 36 in half, and you get 18.
hope this helps!
